Tango would depending on the situation, if someone was attacking me she's definitley try her very best to stop them but if someone just broke into the house she'd probably bark and the hide nehind me lol (she's not the bravest dog in thw world...). Keeva and Winston would NEVER let anyone just walk in the door uninvited let alone attack someone in the family, they're both very protective of their home and family. Tia's too much of a chicken, she'd probably just run and hide in the corner until she felt it was safe to come out (definitely not your typical Dachshund)...
